The golfers versus frogs and garter snake battles continue at Sharp Park, with yet another lawsuit filed against the city-owned golf course in Pacifica.

The latest legal missive, fired off by the Wild Equity Institute, the Sequoia Audubon Society and Save the Frogs, charges that the Recreation and Parks Department’s plan to clear reeds and sediment from a pond and waterway at the golf course is bad news for the threatened California red-legged frogs and San Francisco garter snakes that call the marshy areas home.

“This senseless project will destroy critical wetlands, harm endangered species and cost taxpayers over $1 million to implement,” Brent Plater, executive director of the Wild Equity Institute, said in a statement. He argued that a less-invasive plan exists, “but San Francisco has refused to consider this alternative.”

Plater and other environmentalists have long called for the city to abandon the golf course and let it revert to the marshlands and lagoon that covered the site before the course was built in 1932. A suit looking to close the course was dismissed in 2012 after the U.S. Fish and Wildlife Service determined the threatened species could co-exist with the golfers.

This latest dispute involves environmentalists’ call for a full environmental impact report on the city’s rehabilitation plans for parts of the course. The city Planning Commission and the Recreation and Park Commission, both agreed the lengthy and expensive review process was unnecessary and the Board of Supervisors rejected an appeal on a 7-4 vote on March 25.

City officials say that the project will not increase the amount of water pumped from the course and will provide additional habitat for the frogs and snakes.

The suit was filed in San Francisco Superior Court. No hearing date has been set.
